  Patricia MartinezAug 1, 2025
  If the Omnicharge DC is not working, there could be several reasons: * There may be no input voltage. In this case, check the wiring and input fuse. * The input voltage may be too low. Verify the input voltage, adjust the input voltage settings, or start the engine. * There might be no positive signal on the main On/Off control wire. Check the wiring, fuses, and the status of the engine run signal. * There could be a positive signal on the BMS input. Verify the output battery BMS status. * The input battery condition might be very poor, requiring a battery replacement.

Why is my tbs electronics Battery Charger not charging the battery to its maximum capacity?
- D
  Daniel BuckleyAug 6, 2025
  If the battery is not being charged to its maximum capacity, consider the following: * The absorption charge voltage setting may be incorrect. Check the battery type selection for the correct setting. * The charge current setting might be incorrect. Ensure the maximum output current setting is at the maximum level, verifying this is allowed by the battery manufacturer. * There could be too much voltage loss in the battery cables or connections. Ensure the battery cables have a sufficiently large diameter and that all DC connections are solid.
